There is a whole new area of pain relief being offered in the form of cold laser therapy. The uses for this non-invasive therapy are rapidly growing: the laser can be successfully used for treatment of musculoskeletal pain, neck pain, back pain, extremity pain, post surgical pain. Literally in one minute you can have pain relief, reduced inflammation and muscle spasms while accelerating recovery.
The cold laser, or low level laser, utilizes specific wavelengths of light to interact with tissue. Non-thermal photons of light that are emitted from the laser pass through the skin layers (the dermis, epidermis, and the subcutaneous tissue or tissue fat under the skin). This light has the ability to penetrate 2 to 5 centimeters below the skin.
There are no unsafe side effects to the cold laser. It can be used on humans and animals easily.
